Computational Modeling of Signaling Pathways Mediating Cell Cycle Checkpoint Control and Apoptotic Responses to Ionizing Radiation-Induced DNA Damage

, 2011
The shape of dose response of ionizing radiation (IR) induced cancer at low dose region, either linear non-threshold or J-shaped, has been a debate for a long time.

Shielding for Critical Organs and Radiation Exposure Dose Distribution in Patients with High Energy

, 2002
High energy photon beams from medical linear accelerators produce large scattered radiation by various components of the treatment head, collimator and walls or objects in the treatment room including the patient. These scattered radiation do not provide

The Adaptive Response and Protection against Heritable Mutations and Fetal Malformation

, 2006
There are a number of studies that show radiation can cause heritable mutations in the offspring of irradiated organisms. These “germ-line mutations” have been shown to occur in unique sequences of DNA called “minisatellite loci”. The high frequencies of

The prognostic and therapeutic significance of biological molecular markers in human anorectal carcinomas treated with 5'fluorouracil chemoradiation.

, 2005
Advances in tumour biology have led to studies of new biological markers, which may predict treatment response and clinical outcome independently of standard clinicopathological variables.

Nonlinear Dose-Response Relationship in the Immune System following Exposure to Ionizing Radiation: Mechanisms and Implications

, 2003
The health effects of low-dose radiation (LDR) have been the concern of the academic spheres, regulatory bodies, governments, and the public. Among these effects, the most important is carcinogenesis.

Spatiotemporal dynamics of the DNA double strand break marker 53BP1 after exposure to ionising radiation

, 2012
This thesis was submitted for the degree of Doctor of Philosophy and was awarded by Brunel University53BP1 is known to be involved in the DNA damage response and has been shown to localise into discrete foci at the site of DNA double strand breaks (DSBs)

Evaluation of method for grading late photographic change in breast appearance after radiotherapy for early breast cancer

, 2008
AimsSerial photographs have been collected prospectively to evaluate the effect of radiotherapy on normal tissues in the breast. The aim of this study was to compare two methods of scoring radiation-induced changes.Materials and methodsFive-year ...

On microdosimetry of neutrons of selectable energy in mixed (n,y) fields

, 2012
Biological damage of tissue due to intermediate energy neutrons is generally known to be very important in radiobiology and radiation protection. However, there is no suitable method to determine the quality of these neutrons in particular in the working
